Coral Clones and Genetic degradation?

[Snaz]

I know there are some clever people here so I thought I would ask. I'm thinking that when we frag a coral we are of course cloning the organism and thus copying genetic defects to the new organism. Correct? If true then if we just keep making clones of clones of clones then eventually the corals become weak because they have little or no chance to repair DNA/RNA?

With sexual reproduction you get all sorts of nifty DNA recombinations, repairs and evolutionary benefits which I don't think you get with cloning.

So is my hypothesis correct? Are we producing weak corals as a result of cloning?

Am I out to lunch? Is infinite cloning possible?
